Abstract: WHITE LIGHT HANDLEABLE                   PHOTOGRAPHIC MATERIALS                      Abstract of the Disclosure Many photographic materials must be handled under special lighting conditions in order to prevent exposure of the material.  The use of large concentrations of bleachable light absorbing layers over the photosensitive emulsion tends to leave an undesirable residual stain. The inclusion of a specific class of low intensity recipro-city failure inducers to silver halide emulsions enables the emulsions and their photographic articles to be safely handled under white light conditions.

Abstract: Abstract of the Disclosure Improved aluminum alloy products are fabricated from an improved alloy broadly containing .4 to 1.2% silicon, .5 to 1.3% magnesium, . 6 to 1.1% copper and .1 to 1% manganese.  The alloy is treated at very high temperatures, approaching the solidus or initial melting temperature, to provide the improved performance.          Thereafter, the alloy is shaped as by rolling, extruding, forging and other known aluminum wrought product-producing operations.  In the solution heat treated, quenched and artificially aged temper products so produced exhibit very high strength in comparison with 6XXX aluminum alloys,  together with very high toughness and impact and dent resistance   along with substantial corrosion resistance properties.  In addition, the artificial aging response of the improved products enables use of high temperature, low cost aging treatments without risk of overshooting or undershooting the required or desired properties.

Abstract: ABSTRACT OF THE DISCLOSURE         A safety valve which prevents undesired fluid flow while conducting hydraulic workover or snubbing op-erations on a well.  The safety valve includes three separate valve portions for blocking fluid flow.  A poppet valve can be opened and closed from the well surface. Elastomeric sealing elements form a fluid barrier with the exterior of the work string.  The work string itself opens and closes a flapper valve.  The poppet valve allows fluid flow to bypass the elastomeric sealing elements.

Abstract: ABSTRACT OF THE DISCLOSURE The procedure described is based on a computa-tion of the rotor emf of the asynchronous motor and hence of the slip or of a slip-proportional current component as obtained solely from measurements at the terminals.  Th instantaneous values of the required stator voltage or of the required stator current are formed with the computed signals either via a data-supported regulating circuit or by direct orientation on the space vector of the rotor emf, and fed with the aid of a fast electric controller to the motor.         Using the described procedure,  it is possible, among other things,  to obtain torque or rotational speed control with good dynamic behavior.  The procedure has the advantage of requiring low parameter sensitivity and the capability of dispensing with sensors on the motor.

Abstract: Abstract A method of and apparatus for collecting peat from a peat field. The peat is loosened from a peat field in layers, a problem to to be resolved being how to avoid mixing of the drier surface portion and the lower moister peat layer together. To resolve this problem, the peat to be lifted is loosened from its bed by fastening it to a filter surface by means of negative pressure and by removing the peat from said filter surface after the displacement of uplifting by means of positive pressure. The apparatus is provided with peat layer loosening means, compris-ing a drum (1) coated with a filter material (8) and provided with perforations and internally divided into negative and positive pressure chambers (2 and 3). The peat layer that is fastened to the filter surface (8) can be sheared to form a top and a bottom layer, whereby the bottom layer can be allowed to drop back on the field to dry.

Abstract: ABSTRACT            In the method of providing a coal-gas supply  a carbon-carrier  is converted , by the addition of oxygen drawn in gaseous phase from an oxygen supply pipe,  into a coal-gas which is conducted to the consumers.            In order to ensure  a continuous supply to the consumers a part-stream of the coal-gas output produced during coal gasification  is liquefied and stored in this form. At the same time  oxygen is withdrawn from a store where it is stored in the liquid phase   and evaporated. In the event of failure or stoppages in coal-gas production the stored quantity of coal-gas is progressively evaporated and conducted towards the consumers. At the same time the oxygen is drawn from  the oxygen supply ,liquefied and stored in this phase.   Instead of coal-gas another fuel-gas may be used, e.g. natural gas.

Abstract: Abstract:    A gas sensor includes a layer of a sensitive material formed with spaced electrodes on an electrically insulating substrate, the electrodes being electrically connected to the layer.  The layer is formed of a porous film consisting of a uniform mixture of a p-type compound oxide semi-conductor with a perovskite type of crystal structure as the major ingredient and one or more of vanadium, niobium, tantalum and/or compounds thereof as minor ingredients. The minor ingredients are contained in the layer in an amount of 0.01 to 5% by weight, based on the weight of the p-type compound oxide semiconductor, and are incorporated into the layer by diffusing them into the layer.  The gas sensor exhibits a small change with time and a reduced tailing effect attendant on variations in the gas combustion.  As a result, it is possible to effect measurement, detection and control with a high degree of reliability.

Abstract: ABSTRACT     This invention provides a hot-mix asphalt recycling processes for reconstituting and upgrading old road materials.  In usual hot-mix plants the asphaltic material is heated by a naked flame.  Residual bitument in the asphalt is exposed to the naked flame from the burner, which can seriously damage the bitument and render it largely worthless.  In order to reduce wastage, the invention provides for heating of aggregate in a heating zone, and supplying of the heated aggregate, usually cold reclaimed asphalt, and suitable binder material to a substantially flame-free mixing zone.  By mixing these consitutents in that zone, it is possible to produce a usable hot asphalt pavement mix with reduced asphalt wastage.
